Molecular recognition continues to be an area of keen interest for supramolecular chemists. The investigated [M(L)2]2+ metallo-ligands (M=PdII, PtII, L=2-(1-(pyridine-4-methyl)-1 H-1,2,3-triazol-4-yl)pyridine) form a planar cationic panel with vacant pyridyl binding sites. They interact with planar neutral aromatic guests through pi?pi and/or metallophilic interactions. In some cases, the metallo-ligands also interacted in the solid state with AgI either through coordination to the pendant pyridyl arms, or through metal?metal interactions, forming coordination polymers. We have therefore developed a system that reliably recognises a planar electron-rich guest in solution and in the solid state, and shows the potential to link the resultant host?guest adducts into extended solid-state structures. The facile synthesis and ready functionalisation of 2-pyridyl-1,2,3-triazole ligands through copper(I)-catalyzed azide?alkyne cycloaddition (CuAAC) ?click? chemistry should allow for ready tuning of the electronic properties of adducts formed from these systems.

We describe a new approach to acid chloride synthesis via the palladium-catalyzed carbonylation of aryl iodides. The combination of sterically encumbered phosphines (PtBu3) and CO coordination has been found to facilitate the rapid carbonylation of aryl iodides into acid chlorides via reductive elimination from (tBu3P)(CO) Pd(COAr)Cl. The formation of acid chlorides can also be exploited to perform traditional aminocarbonylation reactions under exceptionally mild conditions (ambient temperature and pressure), and with a range of weakly nucleophilic substrates.

The preparation of bimetallic nanoparticles with controlled size, shape, and composition remains a difficult task, and reproducible methods are highly desired. Here, we report the codecomposition of Ni(cod)2 and Pd 2(dba)3 organometallic precursors in the presence of hexadecylamine (HDA) and hydrogen as an efficient approach to get size-controlled bimetallic nickel-palladium nanoparticles. Presynthesized nickel-palladium nanoparticles of different Ni/Pd ratios were further used for the preparation of supported catalysts by the sol-immobilization method onto a magnetic silica. The obtained supported catalysts were investigated in the hydrogenation of cyclohexene and compared to Ni and Pd monometallic catalysts. The catalysts prepared with a 1:9 Ni/Pd molar ratio achieved the highest initial turnover frequency > 50000 h-1, providing higher activity than the pure Pd monometallic counterpart. This represents an important saving of noble metal. Moreover, the magnetic separation allows excellent separation of the catalyst from the liquid products without metal leaching and exposure to air, leading to an efficient recycling.

Palladium(0)-catalyzed reaction of allene-substituted allylic carboxylates 3-8 employing 2-5 mol % of Pd(dba)2 in refluxing toluene leads to the carbocyclization and elimination of carboxylic acid to give bicyclo[4.3.0]nonadiene and bicyclo[5.3.0]decadiene derivatives (12-17). The carbon-carbon bond formation is stereospecific, occurring syn with respect to the leaving group. Addition of maleic anhydride as a ligand to the above-mentioned procedures changed the outcome of the reaction, and under these conditions 3-5 afforded cycloisomerized products 21-23. The experimental results are consistent with a mechanism involving oxidative addition of the allylic carboxylate to Pd(0) to give an electron-deficient (pi-allyl) palladium intermediate, followed by nucleophilic attack by the allene on the face of the pi-allyl opposite to that of the palladium atom. Furthermore, it was found that the Pd(dba)2-catalyzed cyclization of the trans-cycloheptene derivative (trans-8) can be directed to give either the trans-fused (trans-17) or the cisfused (cis-17) ring system by altering the solvent. The former reaction proceeds via a nucleophilic transallene attack on the (pi-allyl)palladium intermediate, whereas the latter involves a syn-allene insertion into the allyl-Pd bond of the same intermediate. The products from the carbocylization undergo stereoselective Diels-Alder reactions to give stereodefined polycyclic systems in high yields.

The di-cyanovinyl-based small molecules were successfully used as non-fullerene acceptors in high-performance organic solar cells. However, the field-effect performances of these types of small molecules are still rarely studied. In this paper, two acceptor-donor-acceptor (A?D?A) small molecules with fuse ring as donor and strong electron-withdrawing 2-(2-oxindolin-3-ylidene)malononitrile derivatives as acceptors were synthesized and characterized for use in solution-processed organic field-effect transistors (OFETs). The new molecules had deep lowest unoccupied molecular orbital energy level (? ?4.0 eV) for marching the electron transport and exhibited n-type charge transport characteristics. The OFETs based on the small molecules exhibited the highest electron mobility of over 3 × 10?3 cm2V?1s?1. This work indicates that di-cyanovinyl-based small molecules can also be applied in n-type OFETs.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C51H42O3Pd2, you can also check out more blogs about52409-22-0

Subnanocatalysts (SNCs) containing various noble metals (Cu, Ru, Rh, Pd, or Pt) with sizes of approximately 1 nm were synthesized using dendritic poly(phenylazomethine)s as a macromolecular template. These materials exhibit high catalytic performance during toluene oxidation without the use of harmful solvents or explosive oxidants, resulting in the formation of valuable organic products, including benzoic acid as the major product. In particular, Pt19 SNC with a narrow particle size distribution exhibits extraordinary catalytic activity, with a turnover frequency of 3238 atom?1 h?1, which is 1700 times greater than that obtained by commercial Pt/C catalysts.

The transition metal catalysed reactions of benzaldehydes and benzylideneamines with disilanes have been investigated. Palladium phosphine complexes catalyse the double silylation of the C=O bond in benzaldehydes and the C=N bond in benzylideneamines with 1,2-difluoro-1,1,2,2-tetramethyldisilane to yield alpha-(fluorodimethylsilyl)-alpha-(fluorodimethylsiloxy)toluene and N-methyl-N-(fluorodimethylsilyl)-alpha-(fluorodimethylsilyl)benzylamine respectively. When less activated disilanes such as 1,2-dichloro- and 1,2-dimethoxy-1,1,2,2-tetramethyldisilane were employed, the palladium phosphine complexes were less active and selective, resulting in extensive side reactions inclusive of 1,2-disiloxy-1,2-diphenylethane formation. The reaction of benzophenone with the difluorodisilane formed 2,2-dimethyl-4,4,5,5-tetraphenyl- 1,3-dioxa-2-silacyclopentane without affording the corresponding simple double silylation product. The formation of side products such as 1,2-disiloxy-1,2- diphenylethane in the reaction of benzaldehyde and 2,2-dimethyl-4,4,5,5- tetraphenyl-1,3-dioxa-2-silacyclopentane in the reaction of benzophenone appears to suggest intermediacy of radical and silylene species. Tris(dibenzylideneacetone)diplatinum-etpo (etpo = 4-ethyl-1-phospha-2,6,7- trioxabicyclo[2.2.2]octane catalyst system was more active for unactivated disilanes, catalysing double silylation of benzaldehydes with hexamethyldisilane. The same catalyst system was found to catalyse the ortho silylation of benzylideneamines with disilanes via intramolecular C-H activation; both mono- and bis-silylated products were obtained. Reaction rates and product distributions are rationalised in terms of the steric and electronic properties of the disilanes, substrates and the catalyst used. The Royal Society of Chemistry 2003.

Palladium complex PdCl2(dppf) and nickel complex NiCl2(dppe) catalyze cross-coupling of unsaturated aryloxy carbohydrates with phenylmagnesium bromide. The nickel catalyst leads to inversion of configuration at the anomeric center while only retention occurs in the case of the palladium catalyst. This quite unusal retention is probably due to the influence of the ring oxygen atom.
